Birmingham Midshires is a trading name of Bank of Scotland plc (part of Lloyds Banking Group). It is headquartered at Pendeford Business Park, Wolverhampton and has 67 offices throughout England. Between 1989 and 2004, it also had an office located in Cardiff in South Wales, but the operations from this office were moved to Pendeford to make way for a Halifax branch, which still operates today. Previously, Birmingham Midshires was a building society, known as the Birmingham Midshires Building Society.

The Birmingham Midshires was formed in 1986 by the merger of the Birmingham and Bridgwater and the Midshires Building Societies. These societies could trace their roots back to 1849 and were themselves formed by the mergers of the following societies: Liverpool Building Society, Wolverhampton and Mercia, Bristol Equitable Permanent Benefit, Swansea & Gower Permanent, and the Warrington Workingmens' Permanent.

In 1999, the Birmingham Midshires Building Society agreed to a takeover bid from the Royal Bank of Scotland. However the deal collapsed when Halifax plc tabled a more lucrative offer. Halifax itself became a part of HBOS plc when it merged with the Bank of Scotland in 2001. In 2007, it became a division of Bank of Scotland plc following a reorganisation in the HBOS Group.

On 15 September 2005 Birmingham Midshires announced it was planning to close 48 of its 67 branches, through a phased programme concluding in March 2006, and the conversion of the remaining outlets to the Halifax brand. Customers were given the option of banking at their nearest Halifax branch and the 470 full and part-time BM employees are to be offered an alternative role at the company or within the wider Halifax branch network.

In 2008 HBOS plc was taken over by Lloyds TSB and is now part of the newly formed Lloyds Banking Group. Its main headquarters were rebranded as Lloyds following different sectors and work being moved to and from the site.

Birmingham Midshires offers a range of specialist mortgage and savings products. When Birmingham Midshires became part of the Halifax in April 1999, it had savings balances of £5.9 billion and mortgage assets of £9.2 billion. BM savings balances have doubled since then to £12 billion; mortgage assets have more than trebled to over £32 billion.
